Dopamine PowerPoint Presentations - PPT
Interest in dopamine was intensified by the realisation that dopamine had an important role in the pathogenesis or drug treatment of certain brain History diseases eg Parkinsons disease schizophrenia This lead to much research on the sites of action

Always Changing. Experience Dependent. A Reflection of our Experiences. What Activates a Neuron?. Thoughts, Feelings Behaviors ( experiences) . The neurotransmitters attach to the dendrites and this results in an electric charge ( action potential) sent down the axon of the neuron! .
Prediction is important for action selection. The problem:. prediction of future reward. The algorithm:. temporal difference learning. Neural implementation:. dopamine dependent learning in BG. A precise computational model of learning allows one to look in the brain for “hidden variables” postulated by the model.
Substance abuse. Limbic . system creates an appetite that drives you to seek out those things. .. The reward circuitry is activated—with dopamine carrying the message. . The result is less dopamine signaling in the brain, what the scientists call “down regulation.” .
